Abuout Download big file(Like *.avi)

Question

Hi,all:
Sorry,my English is not good.
I have a problem about jsp download big file,
The file's real name is not same as it's save name.
This is the JSP code:
FileInputStream file = null;
BufferedInputStream bis = null;
ServletOutputStream aaa = null;
BufferedOutputStream bos = null;
try
file=new FileInputStream(DLNAME);
bis = new BufferedInputStream(file);
response.setContentType("APPLICATION/OCTET-STREAM;charSet=Shift_JIS");
response.setHeader("Content-Disposition", "attachment; filename=\"" + filename + "\"");
aaa=response.getOutputStream();
bos = new BufferedOutputStream (aaa);
byte[] buff = new byte[2048];
int bytesRead=0;
while((bytesRead = bis.read(buff, 0, buff.length))!=-1)
bos.write(buff, 0, bytesRead);
file.close();     
bis.close();
aaa.close();
bos.close();
catch(IOException e){System.out.println(e.getMessage());}
catch(Exception e){System.out.println("ddddd");}
when the client download file,if he select save file and no cancel, the jsp can work well.
but if he select turn of or cancel the process the web page is so slowly.
pleas help me!!!
